I am a landlord of a single dwelling home in Peoria, Arizona. I had a leak in tenant's home and insurance company allowed restoration company to clean up the wet mess, dry the area, etc. The company was supposed to then deal with insurance company and give estimate for repairs. The restoration company said they don't do estimates and the insurance company said they needed it to proceed. The insurance company eventually contacted another contractor, paid me the claim for the work done by restoration company and the invoice for the company that did the repairs...but it took 10 weeks because the restoration company and insurance company got into stalemate. I want to pay less than 100% of restoration company's invoice due to the breach that the restoration company was going to take care of "everything" Instead my tenants are angry and want rent rebate for living without the master bathroom for 10 weeks. . The restoration company says they will file a lien if I do not pay 100% of their invoice. How do I challenger the lien. The restoration company will not negotiate. Thank you for your help.
